In reply to Tim5Cclimbing:
Congratulations on producing a distinctly atypical blog; it come across as a humorous piss-take of all those 8a dudes who take themselves sooo seriously and there could even be some useful content: e.g. the moonboard adaptation
Its all explained quite well - except routing down into the 2nd 18mm contreplaque: I can't believe your machine can do this in one pass even if it is a Festool (Nice Kit!). I would expect to make 3 passes to get through this depth.
Anyway well done for taking initiative. If you haven't room a tome for a full sheet plywood wall its well worth having a doorway facility of this ilk.
